The Bridge is a 2D logic puzzle game that forces the player to reevaluate their preconceptions of physics and perspective. It is Isaac Newton meets M. C. Escher. Manipulate gravity to redefine the ceiling as the floor while venturing through impossible architectures. Explore increasingly difficult worlds, each uniquely detailed and designed to leave the player with a pronounced sense of intellectual accomplishment. The Bridge exemplifies games as an art form, with beautifully hand-drawn art in the style of a black-and-white lithograph.

Combining action and strategy in a unique way, Sang-Froid: Tales of Werewolves transports you into an epic folktale co-written with best-selling Canadian author Bryan Perro (Amos Daragon, Wariwulf), in which two feuding brothers will have to put aside their differences to save their sister, who is pursued by the Devil himself!

Kentucky Route Zero is a magical realist adventure game about a secret highway in the caves beneath Kentucky, and the mysterious folks who travel it. Developed by Cardboard Computer (Jake Elliot and Tamas Kemenczy), the game features an original score by Ben Babbitt, along with a suite of old hymns and bluegrass standards recorded by The Bedquilt Ramblers. The game is split into five acts, of which the first is available now. Taken as a whole, the Kentucky Route Zero is roughly the length of a summer night. Act I is available now. Act II will be released around April 2013, and the remaining three acts over the rest of the year.

Indebted to the wrong people, and with his life on the line, hired gun Booker DeWitt has only one opportunity to wipe his slate clean. He must rescue Elizabeth, a mysterious girl imprisoned since childhood and locked up in the flying city of Columbia. Forced to trust one another, Booker and Elizabeth form a powerful bond during their daring escape. Together, they learn to harness an expanding arsenal of weapons and abilities, as they fight on zeppelins in the clouds, along high-speed Sky-Lines, and down in the streets of Columbia, all while surviving the threats of the air-city and uncovering its dark secret.

When the clock strikes midnight, its meat night in Daniels hemisphere. Although the edibility of demon flesh still has to be explored for the bigger part of mankind, Daniel knows that one already. Join Daniel in his newest adventure of carnival carnage with new enemies, weapons, and maps!

Official 1.001 Mouse Aiming For Those Who Stood And Fought(Released February 19th, 2013)

Fixed a bug that could occasionally cause exceptions to be thrown when first generating the interior of a new building. - Thanks to windgen, Vatticson, and Mick for reporting.

Previously, there was a bug where the "enter NPC movement mode" keybind could work in side view, causing a warning message to pop up. - Thanks to Mick and Penumbra for reporting.

Fixed a minor graphical issue where "molten lava damage" was reporting damage 100x higher than was actually being done to you.

Mouse Aiming Option Added To SettingsAn option has now been provided in the settings menu for "Enable Mouse Aiming." This lets players who find keyboard or gamepad controls to be repugnant to experience the game in some manner. Our view is that this manner is sub-par and watered-down, but we've finally started looking at this as more of an accessibility mode. It's not ideal, but it allows a certain demographic to play who is otherwise unable/unwilling to do so. There is also a corresponding default keybinding set that has been added, which gives you WASD + mouse controls when used in tandem with the above option. Or you can set your own.

Train Simulator 2013 brings to Steam a new standalone route for train enthusiasts to enjoy. London-Faversham High Speed brings together the exhilaration of high speed trains with the more serene classic third rail lines of Kent all in one route, complete with the streamlined Southeastern Class 395.

Departing London St Pancras, the route for Train Simulator passes under the City with Class 395s reaching speeds of 140mph before stopping at Stratford International on the edge of the London 2012 Olympic Park. Speeding through the Essex countryside and under the River Thames, high speed services stop at Ebbsfleet International Station, where power switches from overhead electrification to third rail pick-up. From here, Class 395s cross onto the classic Kent lines, pausing at stations including Gravesend, Rochester and Sittingbourne, before terminating at Faversham.

London-Faversham High Speed is an accurate depiction of a fantastic modern image UK route with stunning scenery through the Kent countryside. It features accurate depictions of London St Pancras Station, Ebbsfleet International Station, Rochester Castle and Cathedral, and the QEII Bridge at Dartford, and many hours of enjoyable and challenging driving.
